11 Specification of Letters Patent.

Application filed May- 8, 1917.

I To all whom it may concern Be it known that I, WILLIAM GRANT WILLIAMs,a citizen of the United States, residing at Columbus Junction, in thecounty of Louise and State of Iowa, have invented certain new and usefulImprovements in Chiropractic Operating-Tables; and I hereby declare thatthe following is a full, clear, and exact description thereof, referencebe ing had to the accompanying drawings, which form part of thisspecification.

This invention is a novel improvement i"n adjustable tables of thegeneral class used by physicians and surgeons and has particularreference to a table for use by chiropractics when operating onpatients.

The object of the invention is to provide a novel table which. will becomfortable to the patient and can be readily adjusted to support thepatient in various positions while being operated upon.

I will describe one practical embodiment of the invention as illustratedin the accompanying drawings to enable others skilled in the art tomanufacture the same, but do not consider the invention restricted tothe specific construction and form of parts illustrated, and have setforth in the claims the essential features of the invention for whichprotection is desired.

In said drawings:

F'gure 1 is a side elevation of the complete table showing the parts inpractically normal position, and indicating in dotted lines some of theextreme positions to which the several cushions may be adjusted. Fig. 2is a topplan view of the table.

Fig. 3 is a plan view of the table with the cushiens, and some of theparts connected theneavith, removed.

Figs. land 5 are detail vertical transverse sections of the table.

Fig. 6 is a detail. V

Referringto the drawings A, B, C and l) represent the adjustable topmembers or sections of the table, which sections are supported ashereinafter described, and independently adjustable. These sect1ons, arepreferably upholstered or cushioned, in any suitable way, to increasethe comfort of the patient resting thereon.

As shown in said drawings the table comprises end frames 1 which arepreferably connected by side bars or rods 1; the frame June it,

Serial No. 167,2?53.

1 may be cast and the side rods 1 be formed of metal pipes or rods, andhave their ends secured in sockets in the frames 1 .in any suitable way.

Mounted upon the side rods-l adjacent one end of the main frame is asupport 2,

hich may he a casting, having sleeves 52 slidably engaging the bars 1and sustaining the support vertically thereon while allowing it to beadjusted longitudinally thereof. The support may be secured in positionon the rods, when adjusted, by any suitable means, as by tap bolts 2engaging the sleeves 2".

Pivotally mounted upon the support 2'is a member S, which may be cast,and upon which the top section D may be supported. This member 3 1shinged on the support 2 so it can tilt longitudinally of the main frame.As shown it is provided with depending lu gs 3 which are transfixed by arod 3 the" ends of which are secured in openings in the upper end of theside members of the supports 2, see Fig. 5.

The member 3 is provided with a segment 3 whichis approximatelysemi-circular and disposed in the longitudinal plane of the mainframe.,-'Tl1is segment is provided on its under side with notches 3 wnich areadapted to be engaged by a bolt at confined in a recess 2 in the lowerside of the sup w port 2, see Fig. 5. The bolt 4 is normally pressedupward by means of a spring 4 confined in the recess 2 and interposedbevtween'the lower end of this recess and a pin 4 on bolt When bolt iisdisengaged from the seg- 11181113 the member 3 and top section D thereoncan be tilted longitudinally of the frame to any desired angleintermediate the two extreme, angles indicated in dotted lines in Fig.1; and when adjusted to the desired position can be held in suchposition by re engaging the bolt t with the related notch 3 in thesegment. The segment may be provided with-limit stops or lugs 3 toprevent its being rocked too far in either direction.

The-member 3 is provided at its sides with perforated studs 3 throughwhich pass guide rods 5 which are connected at their ends to bracketsfastened to the ends of the section D.

The top section D is thus attached to but till Elli) adjustablelongitudinally of end upon support 3; end it Indy belnstencd in envdelower end of bolt l, end sand lever extends transversely of the tableto and beneath both the sleeves 2, beyond which it projects, end isprovided on its outer ends with hand or pedal pieces P by which.eitl'ier end of the lever can be depressed. When one end is depressedits other end acts as e fulcrum. The ends of the lever 4i they be.slotted and guided on thebolts 2 attached to the sleeves 2; and helicalexpansion springs al may be strung on these bolts between their lowerends and the lever l", on solid springs tending'to return the lever l tonormed position after it is depressed.

Slidably mounted on the side hers 1 ed jecent the other end oi": themain frame is a,

second support (3, in general similar to the fill support 2, and havingsleeves 6 engaging the side hens 1*. Mounted in the upper end of thesupport 6 is it her or rod 6 on which are hinged the supports of the topsections A, B and C i As shown the section A is attached to it member 7,see Fig. 3, which member may be cast and has perforated lugs 7 on itsinner end transfixed by the shaft 6 to hinge the member 7 end section Athereon. From the under side of this member 7 depends a,

segment 7 which is provided on its under side with a. series of.notches. 7 any one of which may be engaged with a bolt 8 mpunted in e'chamber 6 in supporth similrir to the bolt 4: in support 2.

The holt 8 may he upheld by e spring 8', and may he pivotelly connected.at bottom to a lever 8 which is provided with hand or foot pieces 8 atits outer ends, and "which to sleeves 6, and upheld by springs 8 on saidbolts, substantially as lever t is supported and upheld. it either endof lever 8? is depressed the'oolt 8 Will he disengeged from segment 7;end then the member '2 and the top section A attached thereto can be adjusted to any desired position intermediate the two extreme positionsindicated in dotted lines in Fig. l.

As shown the top section C is mounted on bars 9 which are hinged on rodh. The section 0 being suitably attached to these rods but suliicicntlyremoved from the section A to cnaiole section B to be located betweenthe sections A end C.

The top section B is shorter then the; sections A and G and ispreferably etteehed to hinge straps 15 by which it is on the rod 6 asshown in Figs. %2 end its stated the several tofhle sections do, I" v Cand D are upholstered. or. cushioned 1irelerobl'y, The section A ispreferably provided with e. centred, longitudinelly die neeaeoe si u.The section it supports the head of .t patient, and it he is lying uponhis face the section a can he removed so the patients nose will not beinjuredduring treatment. The sction B can be adjusted upwardly with thesection C as indicated in dotted lines Fig. l; but when section B isfully lowered, as also indicated in dotted lines in I Fig. i, thesection '6 will be supported by the horns tr of the support 6.

The section C is adjustable between the extreme positions indicated indotted lines in Fig. 1. It is primarily adjusted by I 1. loosening theset screw 10 and ad usting the section C relative to the lever 10, afterwhich it is fastened by setting the screw 10.

If the bolt 12 is in engagement with one of the notches 10 in lever thesection 0 would be rigidly supported, but if it is desired to have ityieldingly supported the bolt 12 is disen aged from the lever 10, andheld disengagec by partially turning it as described, and then thesection C and lever 10 yieldingly supported by the springs 14:, thepressure of such supporting springs being adjustable by turning screw 13to shift the nut .13 toward or from the pivots 11.

The section I) may be adjusted toward or from the section (3, andarranged at any desired longitudinally of the frame to suit persons ofdifferent lengths. The section D preferably has a cut-out portion orrecess d in its inner end. This recess is very important, and protectscertain parts oi the body of a patient lying in certain positions on thetable from injury by contacting with the section while the patient isimdorgoin the treatment that this table is designed or.

- From the foregoing it will be seen that the sections A, C and D areall independently adjustable and can be relatively adjusted to supportthe body of a patient lying upon the table in any desired position. Thesection C can be either rigidly or yicldingly supported. according tothe treatment to which the patient is to be subjected.

'l he abdominal supporting section C can be locked rigid at level or anyangle; and can be lowered out of the way if desired. When in itlowermost position the leg rest section 1) could he moved inward to moreor less overlie the section C.

iii

The cushion a can be reversed to have an The section l can be movedbackward or forward to accommodate patients of difierentheight, and canbe given any dosired. inclination to suit the position it is desired tohave that part of the body resting on section it) assume.

The sections 1) and [loan be "aised or lowered together to any desiredpositions, until section B rests upon the horns t Then the section 0 canhe further lowered independently of B. The section (I can be eitherrigidly sup mrtcd when adjusted by levers 10 and 11, or it can beyicldingly supported by springs 1% and levers l0 and 11; and the tensionor sprmgy condition,

desired by the operator, is obtained by turning the handle 13 to shiftthe nut 13 forward or backward.

lit Will be seen that this table has a wide range of adjustments to suitany position of the patient required in chiropractic operations; and itcan he usedby surgeons and physicians as an operating table, or

readily adapted for such uses.
